Monthly Mean Surface Air Temperature
and Sea-Level Pressure Anomalies

AUTUMN | WINTER | SPRING | SUMMER

Scale

Anomalies are calculated with reference to mean values for the 30 year period 1968-1997. This period was chosen to highlight differences and similarities between the IPY year and present climatic conditions in the Arctic.
